9. Gas Line Piping

Gas supply piping is to be sized and installed properly in order to provide a supply of 

gas sufficient to meet the maximum demand without undue loss of  pressure between 

the meter and the boiler.  Consult with the 

National Fuel Gas Code ANSI Z223.1 

for 

proper sizing of gas piping for various lengths and diameters.

Locate a drop pipe adjacent to, but not in front of the boiler. Locate a tee in the drop 

pipe at the same elevation as the gas inlet connection to the boiler. Extend the drop line 

with a nipple towards the floor and cap to form a sediment trap. Install a shut off valve 

before the tee with sediment trap and a union after the tee before the combination gas 

valve.

When installing the boiler, make sure a pipe compound resistant to the action of 

liquefied petroleum is used.  Check piping for leaks. Always check leaks with a water 

and soap solution.

 DO NOT USE A FLAME FOR CHECKING GAS LEAKS

The boiler and its individual shut-off valve must be disconnected from the gas supply 

piping during any pressure testing of that piping at test pressures in excess of 1/2 psi.
